1. Bi-hole saw kit can cut to a depth of 32mm / 1.3", and the diameter is 139mm / 5-15/32". The package includes a metal hole saw, a hex shank arbor, 2 center drills, 2 springs, and a wrench.
2. The cutting edge is made of high-speed steel, which provides the hardness and wear resistance required for cutting, and can withstand higher cutting temperatures, reducing the risk of breakage and extending the service life of the hole saw.
3. Not only is it capable of cutting wood, plywood, plastic, drywall, soft plaster, sandbag board, acrylic board, and soft metals, it is also suitable for drilling holes to install can lights, recessed lights, ventilation ducts, home improvement or other similar applications in the workshop.
4. Metal hole saw kits can be installed on hand drills, impact drills, bench drills, and CNC drill presses. Before making any adjustments or replacing the hole saw, make sure the drill or drill press is turned off and unplugged.
5. The material to be cut must be clamped firmly to prevent movement or vibration during the cutting process to ensure an accurate cutting position. Avoid applying excessive pressure to the hole saw while working, as this may cause the tool to break or become damaged.
